LIQUID-FUEL BURNER.

Specification of Letters Patent.

Application filed July 28, 1910. Serial No. 574,313.

To all whom it may concern:

Be it known that we, WILLIAM H. BURK and Lnn M. RIGBY, citizens of the United States, residing at Fostoria, in the county of Seneca, State of Ohio, have invented a new and useful LiquidFuel Burner, of which the following is a specification.

This invention has reference to a burner designed more particularly for using crude oil; and it is the object of the invention to provide a novel and perfect form of burner for this purpose, in which the oil is fed in drops through a tube into a bowl in which combustion takes place, the oil being vaporized upon coming in contact with the heated wall of the bowl.

The invention also has for its object to provide perfect means for feeding air into the tube, this air commingling with the oil dropping through the tube, and passing therewith into the bowl.

A further object of the invention is to provide a structure of the kind stated which is simple and without complicated parts, and also to provide the tube through which the oil drops, with a sight glass, through which the feed may be observed.

Other objects and advantages of the invention will be apparent when the nature of the same is better understood, it consisting in the combination and arrangement of parts to be hereinafter described and claimed.

The invention is illustrated in the accompanying drawing forming a part of this specification, in which Figure l is a central vertical section of the burner and part of a stove. Fig. 2 is a horizontal section on the line 22 of Fig. 1.

In the drawing, 5 denotes the top of the heater or stove to which the burner is applied. In the bottom of the stove, on the grate, or any other suitable place, is mounted a bowl 6 having a central raised portion 7 which serves as a spreader for the oil, as will be presently described.

Depending from the stove top 5, is a downwardly tapered tube 10. This tube is open at the top and its lower end is also open, this end of the tube extending sufficiently into the bowl 6 so that it is brought in close proximity to the apex of the spreader 7, the latter being so located beneath the lower open end of the tube, that the oil passing through the tube drops on the spreader. At the top of the tube 10 is an outstanding annular flange 9 which seat-s in an opening in the stove top and thus serves to support the burner.

Mounted over the upper open end of the tube 10, is a cylindrical air chamber 11 the opposite sides of which are entered by air conducting pipes 12, said pipes extending 1n an upward curve from the air chamber, and having their outer ends fitted with suitable dampers 13 for controlling the amount of air entering the pipes.

The lower end of the air chamber 11 is open, and has a reduced and tapered portion let which fits snugly in the upper open end of the tube 10, the taper of the part 14 corresponding to the taper of the tube. The reduced lower end of the air chamber forms an external shoulder 15 which engages the Patented May 16, 1911.

top edge of the tube 10, and thus serves as a support. The top of the air chamber 11 is formed with a nipple 16 to which is fitted a bulb 17 of glass or other transparent material.

At 18 is indicated a reservoir containing the crude oil. A pipe 19 is connected to this reservoir, said pipe leading to the burner, adjacent to which it terminates in a downward bend 20 extending into the bulb 17 through the top thereof. The reservoir 19 is suitably elevated and located to give a gravity feed. In the pipe 19 is interposed a valve 21 for controlling the flow of oil therethrough. In the flange 9 is an opening 22 which is closed by a slide 23. This opening is provided in order that a piece of burning paper or other material may be dropped into the bowl 16 for the purpose of starting the burner.

In operation, the valve 21 is opened, and a small quantity of oil is permitted to drop into the bowl 6. The valve 21 is then closed, and a piece of burning paper or rag is dropped through the opening 22 into the bowl, to ignite the oil therein. The burning oil quickly heats the bowl, so that when the valve 21 is again opened, and the oil drops into the bowl, it is at once vaporized and ignited. The oil is fed drop by drop into the bowl, and upon striking the spreader 7 it is distributed by the latter to facilitate the vaporization. Air to support combustion passes down the tube 10 with the oil, and is mixed with the oil vapor, thus producing a highly combustible mixture. The air enters the tube by the way of the pipe 12 and the air chamber 11, the amount of air being controlled by the dampers 13. By the tapered form of the tube 10, the air is discharged with greater force into the bowl 6, and a more thorough commingling of the air and oil vapor is thereby effected. The drops of oil are visible through the bulb 17, in view of which the feed may be observed at all times, and therefore kept under per feet control.

What is claimed is:

A fuel burner comprising a bowl having a central upstanding portion, a tapered tube having one end dipping into the bowl to secured to the air chamber, and means for supplying liquid fuel to the bulb.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.
